摘要
简单叙述了测试技术的重要地位及其发展前景,着重介绍将声发射、断面收敛、应力测试、沉降观测、水准量测等5种监测技术综合应用于复合坚硬岩石巷道塌陷段的围岩稳定性与安全监控过程中。对监测结果进行综合、系统分析后,对围岩稳定性进行了综合分析与评价,给出了影响该巷道围岩稳定性的关键因素。
The important roles and application prospects of some testing methods are briefly described,including acoustic emission,convergence inspection,stress measurement,subsidence measurement,level measurement in the process of stability and safety monitoring as well as inspecting of subsiding area in a roadway in composite hard rock. In terms of the modern signal analysis technology,the monitoring results and the stability of rock mass are synthetically evaluated,and the location of acoustic origin has been successfully detected according to the acoustic emission regularity. Finally,the key factors to affect the stability of rocks are obtained in subsiding area.
